Real Time Interception And Monitoring Of A DECT Cordless Telephone

G'day. Welcome to the VK8FOES YouTube channel. A few weeks ago, I showcased in a video how it was possible to intercept and monitor voice traffic on a DECT wireless b@by monitoring system due to the manufacturer not implementing encryption and security. In this video, I will be demonstrating how it is possible to do the same on an DECT cordless telephone. What you are seeing here is a VTech branded cordless telephone with the model number of CS6114. This is a North American market DECT 6.0 telephone that was manufactured in the year of 2017 according to the packaging box. The significance of this particular cordless telephone model is the fact that VTech neglected to implement encryption! DECT 6.0 is a slightly different frequency band to Europe/Asia/Australia and is therefore not legal to use in my location, so I will keep this video rather short. Using my smartphone, I proceed to dial the landline telephone number at my premises and answer the call. Gr-dect2 is a GNU-radio flowchart which can decode DECT voice traffic from cordless phones. I then find the carrier frequency the telephone is operating on which generally sits between channels 21 and 25) Australian DECT phones usually hover around channels one to eight. The next thing I do is find the 'part' A bit of explanation is needed for this, RFP stands for ‘radio fixed part’ and is the base station. Simply put, the cradle the handset sits in that is connected to the telephone line. PP stands for ‘portable part’ and is the handset. Gr-dect2 will display the letter 'v' next to each 'part' signifying that voice traffic is present. Selecting the base station part (RFP) will allow the audio from the party on the other end of the telephone call to be heard, and selecting the handset part (PP) will allow the audio being spoken into the cordless telephone to be heard. And here is where the fun begins, because the VTech CS6114 cordless phone does not implement security and encryption, once I select the RFP radio fixed part and speak into my smartphone, the DECT voice traffic is decoded and played back through my PC speakers. Remember, this phone was manufactured and sold back in 2017, not that long ago in the current year of 2022. There must be thousands of these unsecured cordless phone out there being used by unsuspecting people every day. This demonstration shows how much of a valuable tool a software defined radio and gr-dect2 can be for OPSEC. Now for the disclaimers: This video was made for educational purposes only, and to show cordless phone users the potential privacy risk of unsecured DECT and how to test if their voice communications are secure. Attempting to intercept and monitor private communications is illegal and punishable by hefty fines and imprisonment. You have been warned!
